DESAIN KONTROLLER PID FUZZY UNTUK TUNNING PARAMETER UNTUK PENGATURAN KECEPATAN MOTOR INDUKSI TIGA FASA PADA METODE VEKTOR KONTROL

To get constant speed and improve induction motor performance, required a PID controller, but PID controller is difficult to determine gain value of Kp, Ki, and Kd to obtain induction motor performance matching with the one which is wanted. To overcome this thing, applied fuzzy method logic to get gain Kp, Ki, and Kd as according to set value change point and transformation of payload. Logic system fuzzy is designed to has two inputs that is errors and errors delta and it has gain output Kp, Ki, and Kd. Application of PID Fuzzy controller at three phase induction motor with three testing that is testing without a load, testing to tracking set point, and testing with a load either constant a load and also a dynamic load. The system of Speed of three phase induction motor with PID Fuzzy as its controller is got : rise time= 001795 seconds, setling time = 00195 seconds, errors steady state = 02195%. System can follow transformation of set point within 01291 seconds. At condition with a load, recovery time from system is 000773 seconds. Keyword : Induction motor, tuning parameter, PID Fuzz
